The Nsoung long-fingered frog is a small grey, black and blue species that lives along high altitude mountain streams that run through shrub and montane forest vegetation. They shelter in cavities along the stream bank or under large stones. Males call along the stream for mates, and breeding is presumed to occur in the stream, with eggs hatching out into tadpoles. Mating calls are particularly frequent during the dry season and start at dawn. The habitat of this species is not especially threatened at present, but it remains at severe risk of extinction in the future given its very small range and vulnerability to agricultural encroachment, wood extraction, and expanding human settlements.
